Editor’s note

Denver Post photojournalist RJ Sangosti spent time with families in north Denver’s Elyria-swansea neighborhood over the past 18 months to chronicle how they cope with chronic breathing problems in an industrial area that’s now at the heart of the massive Interstate 70 expansion project. This special, visually driven story follows the lives of two families and other community members who often feel that their voices haven’t been heard in the conversation about development as Denver continues to grow.
